You do it at the immigration office closest to where your current TM30 lists your address as. Wherever you moved to a new TM30 was supposed to be filed within 24 hours of you moving in.

Sleeper train to Nong Khai, cross, and come back in time to catch the day train back to Bangkok

you need a lease for wherever you live. A temporary hotel will not qualify, unless you get a long term lease from them. You will enter on a 90 day visa, giving you enough time to open your Thai bank account for the bt400,000 needed in the account for at least two months before you apply for the year extension to meet the financial requirement. It also gives you enough time to arrange your long term living arrangement.

@Callum *******

they didn't reject it. They gave you 60 days to finish your Thai vacation, and return, to finish your application. They are being nice. The normal request from an embassy when they suspect you left the country you applied in before you received it, was to ask for a copy of every page in your passport, including blank pages. You got lucky.

@Phil *******

if that is the case then you will have no problem getting a yellow book, and a pink card, as another form of id.

Anonymous participant the only requirement for verifying the funds again is if you apply for the extension inside Thailand. Those that simply cross the border every 179 days and immediately returned have had no problems, with just a few being asked to show the bt20,000 technically required to enter as a tourist, used when someone sets off their red flags, as they stereotype, and profile, also. No one has been asked to verify the bank account used with a border bounce, or any leaving and returning. The only time is, as I mentioned, if you get the extension inside Thailand.

exactly, with a seven day grace period if you are late filing.

@Ricky ******

it actually has to do with a Bangkok Bank branch in Pattaya that was used by the Chinese to set-up mule accounts to transfer, and launder, the money they were getting from the scam centers in Myanmar, and to a lesser extent agents that were also using that branch for fake retirement fund accounts. Three people were arrested at that branch, including the branch manager. Because of this Bangkok Bank is making sure all accounts are legitimate. In total, including other banks, 180,000+ mule accounts were closed. Also, it is not "three months" the bt400,000 has to be in your account before extending. It is only two months, and has been for the last 7 years.

90 days after you entered the country is the correct date.
